You may have called the version of phaser installed in the phenix path. Type
wich phaser
in a terminal to check it.

Hi:
I am using CCP4 6.0.2, it has phaser contained in this package. When
I use it

In any case, does Nature Methods actually publish any papers that fall
into the category (quote) "custom-designed software necessary for the
method's implementation" where "a software program is the focus of the
report", at least in the area of macromolecular structure determination?
Come to that,
These structures are horrible..
Remember you do not know your spacegroup.
Absences along 0k0 and 00l will be very influenced by the translation.
Sp you need to test all: P21 2 2 P21 21 2P21 2 21 P21 21 21
Run MOLREP using the pseudo translation vector - it is an option in the

We have tried them and had them work for a few proteins that didn't
look hopeful other ways.
The chaperones express well and obviously by gel and, in fact, we had
one protein that was difficult to separate from the Cpn60.
We very carefully follow the instructions on induction that come with
Hi,

articles in materials science, physics, etc. - not everything is as simple

It seems to me to be important in this context to draw the distinction
between _software_ which is about the most ephemeral thing I can think
of (OK maybe butterflies are more so) - e.g. try compiling code

potentially everlast
You are probably referring to the following works:
Caliandro et al, Acta Cryst. D61 (2005) 556-565
and Caliandro et al, Acta Cryst. D61 (2005) 1080-1087
in which they used density modification to calculate phases for
unmeasured reflections, and used the phases to extend the resolution by

Hi all,
I am a first time SHARP user. I have it installed on SUse 10.0 OS and
configured to ccp4-6.0.2. I do not see the option for inputting known
phase information from my .mtz file on the "Global" page, even if the mtz
file has the Hendrickson-Lattman coefficients. Also, in the "Phase
improvemen
Actually I was thinking of a somewhat earlier paper:
Rayment,I. Molecular relacement method at low resolution:
optimum strategy and intrinsic limitations as determined
by calculations on icosahedral virus models.
Acta Crystallogr. A 39, 102 116 (1983).
But thanks for bringing the Caliandro et a

many missing REFLECTIONS are included.
Hello Arti,
To be able to input external phases as HL you have to set the "User
level" in the "Preferences" to "Advanced" or "Expert". I think that also
changes the options you have in the "phase improvement panel".

Isn't automatically included fabricated data for missing reflections
a really bad idea for anisotropic data where most reflections are
"missing" at high resolution? Shouldn't there be a big flashing red
flag alerting the user to what's been done?

Hi,
Anyone has used phser in ccp46.0.2 which is automatically installed with
ccp4? In previous ccp4 edition
I installed phaser seperately and it worked well, but now it seems has some
problems, it cannot read the
input mtz file, I tried several data, all gave the same error information
like b
Hi,
You are almost certainly not using phaser that came with ccp4, but some
other version, e.g. phenix. From the window you start ccp4i from, type
'which phaser'. It should say '/your/path/to/ccp4-6.0.2/bin/phaser', but
it will say something different in your case (e.g.
'/your/path/to/phenix/
